DETO'NATING DEVICE.

Application-filed April 9,

operable mechanism of thisllrind,.which due to its. simple construction will not only be a safe, butalso positive in its. operation, and.

will not be subject to getting out or order.

Another object of my invention is to provide within such device, simpleand positive operating means, adapted to be easily replace-able.

Another object ofiny invention is to provide within such device a stationary cartrid e receiver provided with individual firpins and a rotary hammer arrangement and a starting and stopping device.

The foregoing and further objects will more fully apparent from. the following escription and the accompanying drawings ni g part of this specification and ilusone of the many possible forms of 111-. invention, and in which:

Figure 1 is an elevation of my device partially in section and with half of the cover removed.

' ure 2 is an end view of the. cartridge receiver, seen from within the housing.

Figure 3 is cross sectional viewtaken on line 8-8 of Figure 1.

Referring to the drawings, numeral 1 denotes the base upon which my device is mounted and to which is positively attached a cartridge receiver bloclc2, in which is mounted a stationary cartridge receiver 3, which is preferably detachable from block 2 and may be associated therewith after loading.

. The cartridge receiver is provided with a plurality of bores at, having a cartridge seat 5. The cartridge receiver block 2. is provided with recesses 6 for receiving firing pins 7, corresponding to the number of cartridge bores a.

The firing pins are preferably provided with a flange, indicated at 8, against which 'vided. a bearing lo 1923. Serial. No. 622.520.

bears with .oneof its ends spring its oti'ier end bears against end 11 of the firing pin.

By means of spring 9 the firing pin is held in position abovethe percussion cap of the cartrid 'e. not-shown, in the drawing.

Attached to block 2 at the opposite side from the cartridge receiver, is attached cam plate 13, provided witha plurality of apertures; tor permitting pins 7 toprotrude ierethrough and which are pressed a ainst n u n b v y spring. 9. The plate is provided w th s 4 ed from each other ant. in. which, spaces it ie'. tiring pins 7 are. located. At the center of block 2 and caniplate .13. there is prohousing one end shaft 16, which latter passes substantially parallel to base plate 1, into another bearing. 17 provided in end platelS attached also to'base 1. Shaft 16. protrudes through. end plate 18 d attached to. its protruding end, is a winged handle 19 provide l tl1e purposeof which will be explainedlater.

.ltotatably mounted on" the shaft 16. is a drum 20 having end plates 21 and. 22. Tithin the drum and wound about shaft 16 is a power spring 23, one end 2% of which is secured toshaft 16 the other end 25 being anchored .in end plate 21 of the drum.

Mounted insidev plate ofthe drum is a pin upon which slides a cylinder 27 provided with a flange 28. rllxtending' from the latter is a hammer pin 29, which, together with the cylinderE YZ, comprises the hammer of my device.

Against flange 28 and end platef22 of the drum bears an expansion spring 30 adapted to press cylinder 2'? in the direction of the earns 14.

Provided also in the end plate 22 is an aperture 31 for receiving a locking pin 32 of the 'electroniagnet 33 actuated bythe current passing through coil 34 from battery indicated at The circuit comprising coil 34 and battery 35 and the conduits 3.6 secured to posts 37, is controlled by a switch or other contact ineans indicated at 38.

Extending from electro-inagnet 33 at the opposite side of locking pin 32'is a guide pin 2-39 provided with a flange 4:0 and extending into guide hole 1-1 provided in end 9, while wall 10 of. the recesses 6 provided with theperi oration 11 in which is guided the firing point alityof annularly arranged. cams 1%,

plate 18 of my device. Spring 40 disposed between flange 40 and end plate 18 tends to always keep locking pin 32 pressed against end plate 22 of drum 20.

Attached to the end plate 22 by means of lugs or any other suitable means indicated at 42 is a gear 43 meshing with a pinion 44, which latter is keyed to a regulator shaft 45 journalled in bearing 46 of brackets 47 and 48 of end plate 18.

Mounted upon regulator shaft 45 is a regulator indicated at 49 adapted to control the speed of the drum 20 when the latter is free to rotate.

For the purpose of arresting the back rotation of shaft 16 when winding the main spring 23, there is a ratchet arrangement of any convenient construction, indicated at 50.

Operation: To set up the alarm, the cartridge receiver 30 is removed from the cartridge receiver block 2, filled with cartridges and replaced to its proper position so that the percussion caps of the cartridges will register with the individual firing pins 7.

Release pin 32 being normally pressed by spring 40 into aperture 31 of end plate 22 of the drum, prevents the latter from moving. Now the handle 19is turned in clockwise direction, in which manner main spring 23 is wound.

WVhen the circuit is closed by contact 38, electro-magnet 33 is pulled into coil 34 and pin 32 releases drum 20 and permits the latter to rotate.

By so rotating the firing hammer is also caused to rotate and the hammer pin 29 will travel upon annular cams 14. When pin 29 starting at the lowermost portion of a cam 14 is caused to travel upon the incline of the cam, cylinder 27 of the hammer is pressed to-' wards end plate 22 of the drum thereby compressing spring 30 until pin 29 reaches the uppermost point of cam 14, in which position the hammer is cooked.

By further movement of the drum, and consequently of the hammer, hammer pin 29 is caused to abruptly leave cam 14 and is propelled by spring 30 against one of the firing pins 7, which latter causes the explosion of the percussion cap of one-charge.

By continuing its rotation the function of the hammer is repeated until all the cartridges are fired. In order to regulate the intervals of firing so as to be as nearly equal as possible, the rotation of the drum is controlled by speed regulator 49 of any suitable construction.

As will be seen my apparatus is extremely simple in its design and operation and positive in its function with all the moving parts in housing 51 and providing ready access to the cartridge receiver, the charges of which are to be replaced.

By providing a stationary cartridge drum the device is greatly simplified, compared with other devices for similar purposes.

WVhile I have shown a specific construction of my invention, be it understood that various changes and improvements may be made without departing from the broad scope of my invention, for which I claim:

1. A detonating device comprising a stationary cartridge receiver, a combination rotary and sliding hammer and means for automatically controlling the latter.

2. A detonating device comprising a stationary cartridge receiver, a combination rotatable and slidinghammer, means for automatically rotating said hammer and means for automatically controlling the speed of operation of said rotating means.

3. A detonating device comprising a stationary cartridge receiver, a combination rotatable and sliding hammer, means for automatically rotating the latter, means for alternately cooking and releasing the hammer, and automatic means for controlling the speed of operation of said rotating means.

4. In a detonating device having a combination. rotary and sliding hammer, annular cocking and releasing means for said hammer, means for automatically operating said hammer, means for controlling the speed of operation of said hammer operating means, and means for controlling the starting and stopping of said operating means.

5. In a detonating device having a stationary cartridge receiver and a combination rotary and sliding hammer, an annular cam arrangement for cocking and releasing said hammer, and electrically actuated controlling means for stopping or starting the operation of the said hammer, automatic means for operating the hammer, and automatic control means for governing the speed of operation.

6. In a detonating device, a stationary cartridge receiver, a rotor, a sliding hammer associated with said rotor, an electrically actuated rotor stop and starting mechanism, an annular cam device for cocking and releasing said hammer, automatic means for propelling said rotor, and automatic means for controlling the speed of the latter.

7. In a detonating device, a. stationary cartridge receiver having individual firing pins, a rotary hammer adapted to actuate said firing pins, means for rotating and means for controlling the rotation of said hammer, means for regulating the speed of rotation, and an annular cam arrangement adapted to alternately cock and release said hammer against the individual pins. v
